CULTIVATO R.

SPECIFICATION forming part of Letters Patent No. 469,109, dated February 16, 1892.

Application filed August 8, 1891- Serial No. 402,132. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM EDWIN WIL- LIAMS, a citizen of the United States, residing at Decatur, in the county of Wise and State of Texas, have invented certain new and useful Improvements in Cultivators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention consists in a new and improved cultivatorin which are combined many novel and valuable features, and the invention will be hereinafter fully described and claimed.

Referring to the accompanying drawings, Figure 1 is a perspective view of my new and improved cultivator. Fig. 2 is a detail side elevation of parts of the cultivator. Fig. 3 illustrates in detail, on an enlarged scale, the bearing-blocks and couplings at the rear ends of the connecting-rods. Fig. 4 illustrates in detail, on an enlarged scale,the bearing-blocks and couplings at the forward end of the con- Fig. 5 illustrates in detail, on an enlarged scale, the spring-couplings of one of the cultivator-blades.

Referring to the several parts by their designating-num'erals, 1 1 indicate the side pieces of the main frame of the cultivator, which are provided each with the three upwardly-projecting bearing-pins 1. From the sides of the frame-pieces 1 extend outwardly the stubaxles 2, on which the supporting-wheels 3 of the machine are mounted.

t indicatesthe rear cross-beam, and 4 th front cross-beam, of the cultivator-frame, each of the said beams being mounted on the end pieces 5, the lower ends of which are formed with the vertical bearings 6 to adapt them to fit on the bearing-pins 1 of the frame sides.

The forward ends of the side pieces 1 are provided with the in'wardly extending bars 7, each of which is formed with a longitudinal horizontal slot 8. Upon each bar 7 is adjustably mounted abearing-block 9, havinga central space 10 to adapt it to fit snugly on its bar 7. This coupling-block is held in place by means of a flanged retaining-block 11, fitting in the rear side of the slot and held in that position by the side pieces 12 of the These side pieces extend hooked frame 12.

through the coupling-blocks from the front side of the same through the longitudinal slot 8 and through the flanged block 11 and have nuts screwed upon their threaded inner ends.

By loosening these nuts the coupling-blocks can be moved nearer together or farther apart to regulate the space between the cultivatorblades.

13 13 indicate the rear coupling-blocks, to which the shovel-standards are attached. On the top of each of these blocks are formed the parallel cars and at the rear upper ends of the front blocks 9 are formed the parallel ears 14. Between the ears 14 and 15 on the rear and front coupling-blocks are pivoted on horizontal pivot-bolts the coupling-links 16, which are precisely similar in construction, each one being formed with a horizontal bearing 16 and a vertical bearing portion 16". These vertical bearings 16 are pivoted in bearings 17, formed at the ends of the upper connectingbars 17. At the lower ends of .the front and rearcoupling-blocks 9 13 are formed the bear ings 18, in which are pivoted on the horizontal pivot-bolts 19 the metal bearing-plates 20, which are formed at their outer ends with the end bearings 21. The ends of these plates 20 are pivoted by vertical pivot-pins in the bearings 22 ,formed at the ends of the lower connecting-rods 22.

From the above description, taken in con nectionwith the accompanying drawings, it

by chains 25 with the upper connecting-rods" 17. It will be seen that by means of these 'levers the rear coupling-blocks, and consequently the cultivator standards and blades, can be raised or lowered, the horizontal pivots of the links'16 and plates 20 permitting the said parts to turn freely to admit of this movement.

26 indicates springs, which are mounted in the rear coupling-blocks, as shown, and which are hitched to the hooks 12. this tongue or reach issecured by-apivot-bolt. upon the center of the rear cross-beam 4, while its forward end passes between the frontbeam are so arranged as to bear upon the pivoted links 16 and plates 20, so that while the rear coupling-blocks have a slight independent movement as the cultivator passes over uneven ground these springs will serve to automatically return the cultivator-blades to their normal operative position.

To the lower end of the standards are secured the foot-pieces 27, having the curved lower ends, as shown. To the lower ends of each foot-piece are centrally pivoted the short curved levers 28, upon the lower end of which acultivator-blade is-mounted. To the rear end of the levers 28 are pivoted the lower ends of flat links 29 29, the upper ends of which are pivoted ,to the levers 30 30. "l hese levers ,arepivoted near their upper ends to the stem or foot-piece 27,-and.their upper ends project ito the rearof said-stem; Acoiled spring-31 is secured at its upperend to the rear ends of the levers 30 and at its .lower end to a fixed projection 32,-aflixed to The upper ends of the links 29 are connected by a stir:

movable obstruction the blade will fly back, as illustrated-by dotted lines in the detail View, Fig. 2, the various connecting links and levers turning, as shown in that view, and as soon as theobstruction is passed the spring 31 willpress the 'parts back to their normal; It will be seen that this:

immediately restore them again to their operati-ve position as soon as an obstruction is passed.

the cultivator is used as a ridingcultivator, the wheel-36 is secured upon the rear part of the reach 34, and the rear cross-beam 4'is arranged as shown in vFigs. 1 and 2; but when it is used as a walking-cultivator the reach is slid forward until the king-boltcan bepassed through a'central aperture '37 in the reach, and theapertured lower ends of the rear beam-supports are seated on the metal bearing-pins 1*, thus giving sufficient room for the handles, which are used when the cultivator is arranged as a walking'cultivator.

it is thought that the construction and operation of my new and improved, cultivator and the advantages of the many hovel features embraced therein will beclearly under stood without requiring further detailed description. t Y c Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s-
